Structural stability and electronic properties of GaAs[Formula: see text]P[Formula: see text] ([Formula: see text]) nanowires (NWs) in zinc-blende (ZB) ([Formula: see text] diameter [Formula: see text][Formula: see text]Å) and wurtzite (WZ) ([Formula: see text][Formula: see text]Å) phases are investigated by first-principles calculations based on density functional theory (DFT). GaAs ([Formula: see text]) and GaP ([Formula: see text]) compound NWs in WZ phase are found energetically more stable than in ZB structural ones. In the case of GaAs[Formula: see text]P[Formula: see text] alloy NWs, the energetically favorable phase is found size and composition dependent. All the presented NWs have semiconductor characteristics. The quantum size effect is clearly demonstrated for all GaAs[Formula: see text]P[Formula: see text] ([Formula: see text]) NWs. The band gaps of ZB and WZ structural GaAs compound NWs with [Formula: see text] diameter [Formula: see text][Formula: see text]Å and [Formula: see text][Formula: see text]Å, respectively are enlarged by the addition of concentrations of phosphorus for obtaining GaAs[Formula: see text]P[Formula: see text] NWs proportional to the x values around 0.25, 0.50 and 0.75.

AbstractTwo new phases of Si8C4 and Si4C8 with the P42/mnm symmetry are proposed. Using first principles calculations based on density functional theory, the structural, elastic, and electronic properties of Si8C4 and Si4C8 are studied systematically. Both Si8C4 and Si4C8 are proved to be mechanically and dynamically stable. The elastic anisotropies of Si8C4 and Si4C8 are studied in detail. Electronic structure calculations show that Si8C4 and Si4C8 are indirect semiconductors with the band gap of 0.74 and 0.15 eV, respectively.
